The Meyers family of Johnston is doing their best to beat the crowds. They were at the Des Moines International Airport on Tuesday.

Their first big stop was going through airport security.

"I'm not worried about it. I'm thinking it might take a little more time," said Suzanne Meyers.

Federal authorities said they're increasing travel security measures and with bigger crowds for the holidays -- that means longer lines.

"Be patient throughout the process, the security officers will do their best to give them a good customer service experience while being thorough and effective in their screening processes," said David Dailey, Federal Security director of Iowa.

Among those processes, more random screening. Officials are also asking people to report any suspicious activity.

"Folks should also be vigilant because passengers themselves are a layer of security and we've seen that in the past so passengers should always be alert," said Dailey.

Des Moines Airport leaders said Wednesday morning will see the biggest rush for them. They expect to screen about 1,500 people between the hours of 6-8 a.m.

"Show up early -- we always say an hour and a half before the flight. You may want to add a little extra time. Parking may be a little bit of a challenge tomorrow," said Kevin Foley, executive director of the Des Moines International Airport.

A challenge for many travelers that's worth the wait.

"My mom is just like, 'Get here as soon as possible,' so I can see her," said Kylie Dagit, of Ames.
